{"version":"1.0","type":"link","title":"Topspin - Newikis","description":"In ball sports, topspin or overspin is a property of a ball that rotates forwards as it is moving. Topspin on a ball propelled through the air imparts a downward force that causes the ball to drop, due to its interaction with the air (Magnus effect). Topspin is the opposite of backspin.","provider_name":"Newikis","provider_url":"https://newikis.com","cache_age":86400,"thumbnail_url":"https://upload.wikimedia.org/wikipedia/commons/3/31/Topspin.png","thumbnail_width":224,"thumbnail_height":200}
